Doctor!
Just watched the pilot of the new Doctor Who series, and I must say it's pretty spiffy. Can't speak for the whole continuity thing, or how well it ties in with other Doctors or how Chris Eccleston does as a performance, but as general sci-fi TV goes, it's darn spiffy. I mean, only Doctor Who could pull off When Mannequins Attack! and leave any degree of respectability.
Also, Billie Piper: Mrowr.
